Title: Cooling of turbine blades of a gas turbine engine
Inventor: GRAHAM PAUL JOHN
IPC: F01D5/18
Filed: 1985-07-24
Abstract: An unshrouded turbine blade (38) comprises an aerofoil portion (44) with a tip (54), remote from the root (40) and closed by a tip cap (66). A suction side wall (46) of the aerofoil portion (44) has a portion (56) which extends radially beyond the tip (54) to form a cooling passage (74) with an L-shaped arm (76) which extends radially from the tip cap (66) and transversely from the leading edge (50) to the trailing edge (52) of the aerofoil. An aperture (80) at the leading edge of the tip cap allows cooling air to be supplied into the cooling passage; and the flow of cooling air from the leading edge to the trailing edge of the cooling passage provides controlled cooling of the portion (56) and tip (54) of the aerofoil. <IMAGE>

Title: Down-hole devices for imparting rotary motion
Inventor: RUSSELL MICHAEL KING
IPC: F03B13/02
Filed: 1985-09-23
Abstract: A down-hole signal transmitter includes an annular impeller 30 mounted on a cylindrical casing 10 and arranged to be driven by the mud flow passing along a drill string, and an annular stator 32 fixed to the casing 10 upstream of the impeller 30. The stator 32 has blades 34 canted relative to the mud flow direction 28, whereas the impeller 30 has blades 36 parallel to the mud flow direction 28. The stator blades 34 thereby cause the mud flow to impact on the impeller blades 36 at such an angle that a small or negligible thrust results at the impeller bearings 56 and 58. It is therefore possible to ensure a long service life for the bearings 56 and 58. <IMAGE>

In the apparatus, when loaded into the supply hopper, the tension springs are separated from one another and then discharged one by one therefrom to the transfer mechanism, where they are rectified in the right and left deviations thereof by the guide member before they are delivered to the setting device. Then, the tension springs are caught and lifted up by the setting device and, during this lifting operation, they are rectified in the direction thereof by the direction restricting member, so that they can be automatically mounted to the seat frame as well as to the pad receiving member. <IMAGE>
Patent GB-2167313-A (GB)
Title: Beer and other beverages dispensed with heads
Inventor: BAMFORTH CHARLES WILLIAM
IPC: B67D1/14
Filed: 1985-11-26
Abstract: In a method of forming or enhancing a head on beer or other beverage, gas is generated in the beverage by a process other than fermentation. Suitable gases are oxygen, nitrogen, hydrogen and methane. In one method glasses into which beer is to be dispensed are washed in water containing hydrogen peroxide and are drained but not dried. Catalase is introduced into the beer. When the beer is dispensed into a glass the hydrogen peroxide is decomposed by the catalase and forms bubbles of oxygen which assist in head formation. In another method a tablet containing dry citric acid and bicarbonate of soda is dissolved in a volume of beer on dispense. Carbon dioxide is produced and assists in head formation.

Patent GB-2192155-A (GB)
Title: Ribbon cassette: ribbon drive
Inventor: HARRY ALAN
IPC: B41J32/00
Filed: 1987-06-16
Abstract: A ribbon cassette, for example having an inked ribbon (29) for a franking machine with a thermal print head (27), has a supply spool (28) and a take-up spool (30). An unwinding force is applied to the ribbon and the take-up spool is driven from the supply spool through a slipping drive such as an elastic, slipping, endless band (32). The slipping drive tends to drive the take-up spool at a speed high enough to maintain ribbon tension. The spools may alternatively be coupled by gears wlth slipping friction clutches between one or both spools and the gears. The force applied to the ribbon may derive from a method of printing in which there is relative movement of the thermal head and the item to be printed, the heated ribbon temporarily adhering to the item. <IMAGE>

Title: Opening and closing vehicle windows etc
Inventor: BORRMANN HANS-ACHIM
IPC: B60J7/057
Filed: 1988-09-07
Abstract: A device for movable parts for closing openings in motor vehicles, having a reversible DC drive motor, a polarity reversing actuation switch located in the motor circuit for supplying a DC voltage to the motor circuit with a poling corresponding to the desired direction of rotation of the motor, a relay with a switch contact located in the motor circuit in series with the polarity reversing actuation switch, as well as a position detection stage, connected to the relay control circuit, for actuating the relay in a reference position of the movable part for the purpose of deactivating the drive motor by opening the switch contact. The relay is a DC relay which opens or closes the switch contact when a first or second voltage level is applied to its control circuit. An electronic relay actuation stage with storage behaviour is connected to the relay control circuit. The relay actuation stage is kept in the set state as a function of the position of the movable part when the polarity reversing actuation switch is closed until the movable part has left the reference position (Fig. 1).

Title: Stowable bulkhead for vehicle body
Inventor: D ANDREA MARIO
IPC: B61D45/00
Filed: 1989-02-22
Abstract: A movable barrier/bulkhead mounting and securing system, especially suited for use in a truck body (10), comprises tracks (14) extending the length of the body and positioned on the ceiling (15); the bulkhead (13) being hingedly mounted on a trolley (16) that can run along these tracks, the bulkhead's gas-strut counterweights (17) being positioned in the depth of the trolley (that is, in the space between the top of the trolley, adjacent the ceiling, and the bottom, up against which the bulkhead hinges when stowed). The bulkhead when stowed adjacent the ceiling activates a friction brake that in use bears against the ceiling (or the trolley track) and so prevents the trolley carrying the thus-stowed bulkhead from moving along the track (Figure 3). <IMAGE>
